Description

The present invention relates to fire extinguishing equipment and a method for managing fire extinguishing equipment.

In recent years, while experts have pointed out climate change due to global warming, several countries around the world are facing the environmental problem of record temperature rise, which can be said to be a typical example of extreme weather. Regardless of the correctness of the reason for the climate change, it is a certain fact that there were many areas in Japan where the maximum temperature of 40 ° C or higher was observed in the summer, at least in Japan. Such a record rise in temperature may promote fatigue or malfunction of fire extinguishing equipment, which has not been expected so far.

So-called package-type fire extinguishing equipment, in which a fire extinguishing agent storage container, a pressurized gas container, a hose, a nozzle, a starting device, etc. are housed in one storage box, has been adopted as an alternative to the indoor fire hydrant equipment. For example, in a package-type fire extinguishing system using a fire extinguisher installed in an environment exposed to the outside air and not air-conditioned, the gas existing in the fire extinguishing agent storage container increases its pressure as the outside temperature rises. In order to cause the fire extinguishing agent to be pressed, the fire extinguishing agent in the fire extinguishing agent storage container is pressed. As a result, there was a possibility that the fire extinguishing agent was discharged from the nozzle via the hose as if it was pressed by the pressurized gas from the pressurized gas container.

Until now, as a countermeasure against the above possibility, a resin plate called a sealing plate has been placed in the flow path from the fire extinguishing agent storage container to the hose so that the extinguishing agent is not released only by the rise in the outside temperature. A technique for preventing an unintended release of the fire extinguishing agent by interposing and sealing the fire extinguishing agent is disclosed (Patent Document 1). The sealing plate is devised so as to be destroyed by the pressed fire extinguishing agent when the inside of the fire extinguishing agent storage container is pressurized by the pressurized gas.

However, when the above-mentioned sealing plate is adopted, it is necessary to regularly or irregularly replace the sealing plate that cannot fulfill its role due to fatigue due to heat cycle due to temperature change during day and night and deterioration of the material over time. .. As a result, the adoption of the seal plate causes inspection work and replacement work of the seal plate in the maintenance and management of the fire extinguishing equipment, and also causes a burden of cost increase.

Further, as described above, the sealing plate needs to have "weakness" to the extent that it can be destroyed by the fire extinguishing agent pressed by the pressurized gas, and thus has the characteristics. It is very difficult to adopt a highly durable sealing plate.

The present invention greatly contributes to the realization of fire extinguishing equipment that is resistant to temperature changes in the environment in which it is installed and repeated temperature changes.

As mentioned above, the adoption of a sealing plate is useful as a temporary solution, but it causes an increase in work load and cost. Further, even if the functionality of the sealing plate itself is improved, improvement of the material and avoidance of complication of the structure while suppressing the cost are high technical barriers. Therefore, the inventor of the present application has worked diligently to create a structure or a structure so that the fire extinguishing agent is not released only by the rise in the outside air temperature without adopting a sealing plate which can be said to be a member which is originally unnecessary.

As a result of many trials and errors and analysis by the inventor of the present application, the gas in the fire extinguishing agent storage container whose pressure may increase as the outside temperature rises is outside the region where the gas is housed and / or the region. A structure and configuration was created that opened to the outside of the flow path communicating with. As a result, the inventor of the present application has found that the above-mentioned problem of preventing or suppressing the unintended release of the fire extinguishing agent with high accuracy can be solved. The present invention was created based on the above-mentioned points of view.

One fire extinguisher facility of the present invention supplies a fire extinguishing agent storage container containing a fire extinguishing agent and a pressurized gas for pressurizing the fire extinguishing agent in the fire extinguishing agent storage container via a first flow path. It includes a pressurized gas container and a second flow path for discharging the fire extinguishing agent to the outside when the fire extinguishing agent is pressurized. Further, in this fire extinguisher facility, when the above-mentioned pressurized gas is not supplied, the pressure increases with the temperature increase of the above-mentioned fire extinguishing agent storage container and / or the above-mentioned first flow path.

In addition, the above-mentioned second valve does not allow the above-mentioned pressurized gas to pass from the above-mentioned fire extinguishing agent storage container toward the second flow path, and the pressure of the above-mentioned gas is the pressurized gas of the above-mentioned pressurized gas. When the pressure is lower than the pressure, it is a valve that allows the gas to pass from the fire extinguishing agent storage container toward the second flow path.

According to the fire extinguishing equipment of the second aspect, the pressure of the gas in the fire extinguishing agent storage container and / or in the first flow path when the pressurized gas is not supplied, for example, as the outside temperature rises. When the amount of gas rises, a part of the gas can be opened to the second flow path outside the fire extinguishing agent storage container by the above-mentioned second bypass flow path and the second valve. As a result, it is possible to prevent or suppress the unintended release of the fire extinguishing agent due to the gas in the fire extinguishing agent storage container pressing the fire extinguishing agent with high accuracy.

<First Embodiment>
FIG. 1 is an explanatory diagram showing an outline of the fire extinguishing equipment 100 of the present embodiment. Further, FIG. 2A is an explanatory diagram showing an outline and operation of the structure of the valve (first valve 60a) in the fire extinguishing equipment 100 of the present embodiment. In each explanatory diagram showing the outline of the fire extinguishing equipment not only in FIG. 1 but also in all the embodiments, the fire extinguishing agent 12 in the fire extinguishing agent storage container 10 is drawn so as to be visible for convenience of explanation.

(Composition and operation of fire extinguishing equipment 100 and first valve 60a)
As shown in FIG. 1, the fire extinguisher equipment 100 of the present embodiment pressurizes the fire extinguisher storage container 10 (typically, a known metal container) containing the liquid fire extinguisher 12 and the fire extinguisher 12. Pressurized gas container 70 (typically a known metal pipe) for supplying the pressurized gas for this purpose via a first flow path 20 (typically, a known metal or resin pipe). A container) and a second flow path 30 (typically a known metal or resin) that is a part of the flow path for discharging the fire extinguishing agent 12 to the outside when the fire extinguishing agent 12 is pressurized. Piping) and.

Here, when the fire extinguishing agent 12 is pressurized, the hose 80 (typically,) communicating with the siphon pipe 32, the second flow path 30, and the second flow path 30 via a metal or resin joint 84 (typically). , A known resin pipe), and the fire extinguishing agent 12 is discharged to the outside via a known nozzle 82. The region (space in which the gas exists) 14 obtained by subtracting the volume of the fire extinguishing agent 12 from the volume of the fire extinguishing agent storage container 10 of the present embodiment communicates with the first flow path 20.

Further, in the fire extinguisher equipment 100 of the present embodiment, when the pressurized gas is not supplied, the pressure of the fire extinguisher storage container 10 and / or the pressure of the first flow path 20 increases as the temperature rises. A gas release mechanism capable of opening a part of the gas in the 10 and / or the first flow path 20 to the outside of the fire extinguishing agent storage container 10 and / or the outside of the first flow path 20 is provided.

More specifically, in the gas release mechanism of the present embodiment, the first bypass flow paths 40a and 40b capable of communicating the first flow path 20 and the second flow path 30 when the pressurized gas is not supplied. (Typically, a known metal container) and a first valve 60a (for example, manufactured by PISCO, model CVLU10-10) provided in a part of the first bypass flow paths 40a and 40b are provided. There is. The pressure between the gas in the fire extinguishing agent storage container 10 and the gas in the first flow path 20 (hereinafter, also collectively referred to as “inside the fire extinguishing agent storage container 10 or the like”) and the gas in the second flow path 30. When the difference is 0.01 MPa or less, the first valve 60a of the present embodiment is a valve that allows gas to pass from the first flow path 20 side to the second flow path 30 side.

Further, the first valve 60a, the second valve 60b, the first open valve 60c, and the second open valve 60d adopted in each of the second to fifth embodiments described later are the first valve 60a of the present embodiment. The same valve as can be adopted. However, as long as each function of the first valve 60a described later is provided, it is possible to adopt an off-the-shelf product different from the first valve 60a as a substitute for the first valve 60a described above. Further, in the present embodiment, the pressure difference between the gas in the fire extinguishing agent storage container 10 and the like and the gas in the second flow path 30 is not limited to the numerical range of 0.01 MPa or less. For example, it is one of the modifications of this embodiment to use a valve that allows gas to pass from the first flow path 20 side to the second flow path 30 side when a pressure difference of 0.2 MPa or less occurs. be.

Further, in the present embodiment, as shown in FIG. 1, the first flow path 20 and the first bypass flow path 40a are connected to one connecting portion (FIG. 1) via a known metal or resin joint (not shown). 1 A) communicates, and the second flow path 30 and the first bypass flow path 40b communicate with each other at another connection portion (B in FIG. 1) via a known metal or resin joint (not shown). ing.

In addition, the first valve 60a has the following two functions (x1) and (y1), as shown in FIG. 2A.
(X1) When a fire extinguishing agent is used for fire extinguishing activity, the pressurized gas supplied from the pressurized gas container 70 (the arrow of "high pressure (pressurized) gas" in FIG. 2A (b)) is the first. Do not pass from the flow path 20 toward the second flow path 30.
(Y1) When the pressurized gas is not supplied, a pressure difference occurs between the gas in the fire extinguishing agent storage container 10 and the like and the gas in the second flow path 30, which is caused by, for example, an increase in the outside temperature or other abnormality. Even so, when the pressure of the gas in the fire extinguishing agent storage container 10 or the like is lower than the pressurized gas pressure (the arrow of “low pressure gas” in FIG. 2A (a)), the gas in the fire extinguishing agent storage container 10 or the like is used. A part is passed from the first flow path 20 side toward the second flow path 30.

In the first valve 60a of the present embodiment, when the pressure of the gas in the fire extinguishing agent storage container 10 or the like is lower than the pressurized gas pressure (“low pressure gas” in FIG. 2A (a)), the valve body 62 is Since it exists between the valve body stopper 64 and the downstream end of the first valve 60a without completely blocking the flow path, the fire extinguishing agent storage container 10 is directed from the first flow path 20 side toward the second flow path 30. It is possible to pass a part of the gas in the same. As a result, the pressure difference between the gas in the fire extinguishing agent storage container 10 and the like and the gas in the second flow path 30 disappears or becomes smaller, so that the unintended release of the fire extinguishing agent 12 is prevented or suppressed with high accuracy. Is possible.

In addition, instead of the first valve 60a of the present embodiment, the spring type valve 260a shown in FIG. 2B is adopted so as to play the above-mentioned roles (x1) and (y1) in the same manner as the first valve 60a. By arranging the valve, the same effect as that of the present embodiment can be achieved. The fire extinguishing equipment that employs the valve 260a is one of the modifications of the present embodiment.

Specifically, when the pressure of the gas in the fire extinguishing agent storage container 10 or the like is lower than the pressurized gas pressure (“low pressure gas” in FIG. 2B (a)), the valve 260a has a force for pushing the spring 266. Due to its weakness, the valve body 262 does not completely block the flow path. As a result, it becomes possible to pass a part of the gas in the fire extinguishing agent storage container 10 or the like from the first flow path 20 side toward the second flow path 30. On the other hand, when the fire extinguishing agent is used to extinguish the fire, the pressurized gas supplied from the pressurized gas container 70 (FIG. 2B (b) pushes the valve body 262 against the urging force of the spring 264. As a result, the valve body 262 completely blocks the flow path, so that the “high pressure (pressurized) gas” arrow) does not pass from the first flow path 20 toward the second flow path 30. Therefore, the first valve 60a of the present embodiment is not limited to the valve body shown in FIG. 2A.

On the other hand, when the pressurized gas is supplied from the pressurized gas container 70 when the fire extinguishing agent is used for performing the fire extinguishing activity, in the first valve 60a, the valve body 62 is a high pressurized gas due to the pressurized gas. The pressurized gas does not pass from the first flow path 20 toward the second flow path 30 because the flow path is blocked by being pushed by the pressure. As a result, the pressurized gas is supplied from the first flow path end 22 of the first flow path 20 in a state where the pressure is substantially maintained, and the pressurized gas is a liquid in the fire extinguishing agent storage container 10. By pressing the fire extinguishing agent 12, the fire extinguishing agent 12 is discharged to the outside via the second flow path 30, the hose 80, and the nozzle 82.

Therefore, in the fire extinguisher equipment 100 of the present embodiment having the above-described configuration, for example, when the pressurized gas is not supplied, the inside of the fire extinguishing agent storage container 10 and / or the first flow path 20 as the outside temperature rises. When the pressure of the gas inside increases, a part of the gas can be opened to the outside of the fire extinguishing agent storage container 10 and / or to the outside of the first flow path 20 by the above-mentioned gas opening mechanism. As a result, it is possible to prevent or suppress the unintended release of the fire extinguishing agent 12 due to the gas pressing the fire extinguishing agent 12 with high accuracy.

<Second embodiment>
FIG. 3 is an explanatory diagram showing an outline of the fire extinguishing equipment 120 of the present embodiment. The fire extinguishing equipment 120 of the present embodiment includes the second bypass flow paths 50a, 50b and the first valve 60b as the gas release mechanism instead of the first bypass flow paths 40a and 40b and the first valve 60a. Except for the point, it is the same as the fire extinguishing equipment 100. Therefore, the description overlapping with the first embodiment may be omitted.

(Composition and operation of fire extinguishing equipment 120 and second valve 60b)
As shown in FIG. 3, in the fire extinguishing equipment 120 of the present embodiment, the fire extinguishing agent storage container 10 and the second flow path 30 can be communicated with each other without passing through the first flow path 20. , 50b (typically a known metal or resin pipe) and a second valve 60b provided in a part of the second bypass flow paths 50a and 50b. The second bypass flow path 50a includes an opening 50c that communicates with the region 14 of the fire extinguishing agent storage container 10.

Further, in the present embodiment, as shown in FIG. 3, the second flow path 30 and the second bypass flow path 50b are connected to one connecting portion (FIG. 3) via a known metal or resin joint (not shown). It communicates in C) of 1.

In addition, the second valve 60b, like the first valve 60a, also has the two functions (x1) and (y1) described in the first embodiment.

As a result, when the pressure of the gas in the fire extinguishing agent storage container 10 is lower than the pressurized gas pressure, the second valve 60b of the present embodiment has the gas from the fire extinguishing agent storage container 10 toward the second flow path 30. It is possible to pass a part of. As a result, the pressure difference between the gas in the fire extinguishing agent storage container 10 and the like and the gas in the second flow path 30 disappears or becomes smaller, so that the unintended release of the fire extinguishing agent 12 is prevented or suppressed with high accuracy. It becomes possible.

On the other hand, when the pressurized gas is supplied from the pressurized gas container 70 when the fire extinguishing agent is used for performing the fire extinguishing activity, in the second valve 60b, the valve body 62 is a high pressurized gas due to the pressurized gas. The pressurized gas does not pass from the fire extinguishing agent storage container 10 toward the second flow path 30 because the flow path is blocked by being pushed by the pressure. As a result, the pressurized gas presses the liquid fire extinguishing agent 12 in the fire extinguishing agent storage container 10 via the first flow path 20 in a state where the pressure is substantially maintained, whereby the fire extinguishing agent 12 is pressed. Will be discharged to the outside via the second flow path 30, the hose 80, and the nozzle 82.

Therefore, in the fire extinguisher equipment 120 of the present embodiment having the above-described configuration, for example, when the pressurized gas is not supplied, the inside of the fire extinguishing agent storage container 10 and / or the first flow path 20 as the outside temperature rises. When the pressure of the gas inside increases, a part of the gas can be opened to the outside of the fire extinguishing agent storage container 10 and / or to the outside of the first flow path 20 by the above-mentioned gas opening mechanism. As a result, it is possible to prevent or suppress the unintended release of the fire extinguishing agent 12 due to the gas pressing the fire extinguishing agent 12 with high accuracy.
